Buchanan, 1023 Cerro Alto, San Antonio, Tex. 78213 Filed May 14, 1965, Ser. No. 455,931 4 Claims. (Cl. 137-360) ABSTRACT OF THE DISCLOSURE A drain fixture for a vertical building wall consisting of a vertical outer plate, a plurality of horizontal tubes secured to and opening through the outer plate, a downwardly and outwardly-inclined hood-like drain spout secured to the outside of the outer plate surrounding the openings of the tubes, the tube openings being located in the upper region of the hood-like spout, and the spout having a relatively long curved top wall, a relatively short bottom wall and sidewalls, the discharge opening of the spout having a horizontally-elongated shape and being in a plane inclined upwardly and outwardly of the plate. An inner vertical plate has openings receiving the inner ends of the tubes. Pipe couplings are threaded on the inner ends of the tubes, bearing clampingly against the inner plate, so that the inner and outer plates can be clamped on a building wall on the opposite sides thereof surrounding an opening in the building wall through Which the tubes extend, so that the plates cover the wall opening. Respective drain pipes are adapted to be threadedly-connected to the pipe couplings.

This invention relates to unitary multiple off-wall drain fixtures.

In various building drain systems, including those of fire-protection sprinkler systems, it is common practice to drill related building walls for several dilferent sizes of drainpipes, and install the pipes therethrough at substantial expense of time and labor, and with results that are functionally adequate, but which are unsightly and are damaging both to the constitution and appearance of the walls.

The primary object of the present invention is the provision of unitary multiple drain fixtures, which embody the necessary number and sizes of pipes, and which require for their installation only the making of a single hole through a Wall, the said fixtures having drain hoods whose drain openings are spaced outwardly from the wall, so as to eliminate or reduce damage to the constitution of and the appearance of the wall, from the fluids drained, the hoods being decorative in appearance.

Another object of the invention is the provision of devices of the character indicated above, which lend themselves to easy and rapid installation, the devices having outside wall-engaging flanges, and inside wallengaging flanges, the latter being readily adaptable to accommodate walls of different thicknesses, and being held in place by pipe couplings threaded on the pipes of the devices, which couplings also serve to couple related system pipes to the pipes of the devices.

In the drawings:

FIGURE 1 is a fragmentary schematic perspective view, partly broken away and in section, showing one form of the device of the invention installed through a wall;

FIGURE 2 is an enlarged vertical section taken on the line 2-2 of FIGURE 1;

FIGURE 3 is a vertical section taken on the line 33 of FIGURE 2;

FIGURE 4 is an outboard elevation of another form of device of the present invention;

FIGURE 5 is a vertical section taken on the line 55 of FIGURE 6; and

FIGURE 6 is a vertical section taken on the line 66 of FIGURE 4.

Referring in detail to the drawing, and first to FIG- URES 1 to 3 thereof, a vertical building wall W is shown, formed therethrough with a single horizontal rectangular opening 10 in which is installed a device A of the invention, which serves simultaneously three in-building system pipes, comprising a relatively large-diameter sprinkler system drainpipe 12, a smaller-diameter alarm motor drainpipe 14, and a still smaller-diameter accelerator drainpipe 16.

The device A comprises a fiat rectangular outside wallengaging flange or plate 18 larger in area than the wall opening, and adapted to bear against the outside surface of the wall W. The plate 18 is formed therethrough with threaded openings, in a triangular arrangement, which consists of an upper opening 22, a lower left-hand opening 24, and a lower right-hand opening 26, in which are respectively threaded the outer ends of a large-diameter system drain tube 28, an alarm motor drain tube 30, and an accelerator drain tube 32, respectively.

The tubes, 28, 30 and 32, are longer than the thickness of the wall W, and have externnally-threaded inner ends 34 on which are threaded the related ends of pipe couplings 36, whose inner ends are threaded, as indicated at 38, on the related ends of the corresponding system pipes 12, 14 and 16, respectively.

The inner parts of the tubes 28, 30 and 32 pass through smooth openings 40 formed in an inner wall-engaging flange or plate 42, of the same size as the outer wall plate 18, and the couplings 36 are threaded on the related tubes to bear against the inner plate 42, so as to draw both the wall-engaging plates tightly against the related surfaces of the wall W.

The outer wall-engaging plate 18 is preferably integrally-formed with a rectangular cross-sectional tubular hood or spout 44 which spacedly surrounds the tube openings 22, 24 and 26, the hood 44 being outwardly and downwardly-curved so that its discharge opening 46, at the lower-end thereof, is both angled away from and spaced outwardly from the outer wall surface 20. The hood 44 has a relatively long outwardly and downwardlycurved top wall 48, a relatively short outwardly and downwardly-angled bottom wall 50, and flat-vertical terminal sidewalls 52. The lower edge 54 of the bottom wall is spaced downwardly from the lower edge 56 of the top wall 48, and both lower edges merge into the outwardly and upwardly-angled lower edges 58 of the sidewalls 52.

The form of the device A shown in FIGURES 4 to 6, is adapted for installation in a wall W having therethrough a cylindrical wall opening 10', rather than a rectangular wall opening 10, and differs from the form of FIGURES l to 3, in having circular outer and inner wallengaging plates 18' and 42, respectively, and in having the outer ends of the tubes 28', 30' and 32' integral with the outer Wall plate 18'. Further, the hood or spout 40 is of downwardly-flared and oval cross-section rather than rectangular cross-section.

It will be evident from the foregoing that suitable wall openings having been made, the devices A and A are capable of easy and rapid installation, are decorative rather than being crude in appearance at the outsides of the walls, and because of the off-wall drainage provided by their spouts, outside wall damage and deterioration in appearance thereof are prevented or reduced.

What is claimed is:

1. A device of the character described, comprising a vertical outer plate having an outer side, a downwardly and outwardly-angled spout fixed to said outer side, said spout having a relatively long outwardly and downwardly-curved top wall, a relatively short outwardly and downwardly-angled bottom wall, and terminal sidewalls,

said walls defining at their bottom edges a horizontallyelongated discharge opening located in a plane inclined upwardly and outwardly from said outer plate, said outer plate being formed with a plurality of openings, said openings opening into the upper part of the spout, respective horizontal tubes having outer ends secured to the outer plate and severally communicating with said openings, a vertical inner plate formed with openings passing said tubes, said tubes having threaded inner ends, and respective pipe couplings threaded on said inner ends and bearing against the inner surface of the inner plate, said couplings reaching inwardly beyond the inner ends of the tubes and being adapted to be severally connected to drainpipes.

2. The device according to claim 1, wherein the outer ends of the tubes are threaded into the outer plate.

3. The device according to claim 1, wherein the outer ends of the tubes are integral with the outer plate.

4 4. The device according to claim 2, and wherein said sidewalls are substantially fiat and vertical and said discharge opening is substantially rectangular.
